ERECTING AND STOWING THE
SWINGAWAY BOOM EXTENSION
General Warnings
Securing the Boom Extension with Tag Line (Rope)
NOTE: A tag line attached to the tip of the extension is
used to control the movement of the boom
extension.
The extension may swing out on its own when you remove
the last connection that held the extension at the side of the
main boom.
You must therefore secure the extension before you begin
the erection procedure.
Secure the boom extension as follows:
• Attached a tag line (rope) at the front of the
extension.
• Have a helper hold the tag line (rope) tight while you
are removing the last connection.
NOTE: If you are alone, secure the other end of the tag line
(rope) on the crane (e.g., on the steps of the
access ladder or to the superstructure. Leave
enough play in the tag line that it is tight only when
you swing the extension towards the main boom
head later in the procedure.
Erecting
1. Fully extend and set the outriggers using normal setup
procedures. Refer to Setting The Outriggers, page 3-30.
2. Position the boom over the front.
3. If extended, fully retract all the boom sections and lower
the boom to minimum elevation to permit ease of
installation of pins and access to the boom nose.
NOTE: The auxiliary boom nose (rooster sheave) does not
have to be removed. However, if reeved, the hoist
cable must be removed from the sheave.
4. Rig either the main hoist or optional auxiliary hoist cable
for single part line with nothing but the wedge socket on
the end of the cable.
5. On the rear stowage bracket Figure 4-14 (Detail B),
remove the pin securing the sliding support in the “IN”
position. Push in on the handle to push the swingaway
away from the rear of the boom and engage the
swingaway anchor fittings with the boom nose
attachment lugs. Install the pin securing the sliding
support in the “OUT” position (Figure 4-14, Detail B).
6. Remove the retainer clips from the right side attachment
pins stowed in the adapter of the swingaway and
remove the attachment pins from the swingaway. Insert
the right side attachment pins through the boom
attachment lugs and swingaway adapter anchor fittings.
Install the retainer clips in the attachment pins.
7. Connect RCL cables:
a. Remove RCL cable end connector (1) Figure 4-8
from extension and route through boom extension.
DANGER
To prevent serious injury or death, always wear personal
protective equipment; i.e., a hard hat, eye protection,
gloves and metatarsal boots.
Before attempting to erect or stow the boom extension;
read and strictly adhere to all danger decals installed on
the boom/boom nose, boom extension, and stowage
brackets to prevent serious injury or death.
Controlling the boom extension during erecting and
stowing procedures is accomplished by raising or
lowering the boom. Failure to control the swingaway could
cause serious injury or death.
DANGER
Always secure the boom extension with a tag line (rope)
on the main boom before removing any connections. This
will prevent the extension from swinging around and
knocking you off the carrier or injuring other persons in the
swing range.
DANGER
To prevent serious injury or death, do not stand on crane
decking until boom extension is secure.
